 ## Building the Tool
 
-The repository includes a `build.sh` script to build the CLI tool. It updates the version in `version.go` and builds the binary.
+The repository includes a `Makefile` to build the CLI tool. It automatically determines the version from Git tags and builds the binary.
 
-To ignore changes made to `version.go` in Git, you can run:
-
-```bash
-git update-index --assume-unchanged version.go
-```
+To build the tool, run the `make` command. The binary will be created as `build/lab-ca`.
